Question #3b5f1

Answer 1

`11.2g`

Explanation:

ok so first you will find the moles in 16.5g of `Fe_2O_3`
so Moles=mass/molar relative mass
by putting the values `mol=16.5/160` the mols will be `0.1`
so by using the equation we know that 1 mol of `Fe_2O_3` makes
2 mols of `Fe` so by using the ratio method `1:2` and `0.1:x` write these one above the other and cross multiply so the mols of `Fe` we will get will be `0.2` then use the formula moles=mass/molar relative mass `0.2*56=mass` the ans will be `11.2g`
